Tuchscherer, Armin Miersch, Claudia Vernunft, Andreas Viergutz, Torsten Kreuzer, Michael Schwarm, Angela <jats:p> The proliferation of blood lymphocytes from nonpregnant, nonlactating heifers was comparable with that of nonpregnant cows in their first lactation. Both low and high levels of β-hydroxybutyrate and low levels of prolactin, but not isoproterenol, reduced the proliferative response of dairy heifers and cows in their first or second lactation. </jats:p> application/pdf https://sonar.ch/global/documents/231539 eng info:eu-repo/semantics/altIdentifier/doi/10.1139/cjas-2017-0143 info:eu-repo/semantics/altIdentifier/issn/0008-3984 info:eu-repo/semantics/openAccess Canadian Journal of Animal Science. - Canadian Science Publishing. - 2018, vol. 98, no. 4, p. 898-901 Food Animals Animal Science and Zoology Effect of immune modulators and lactation number on in vitro proliferation of lymphocytes from nonpregnant dairy heifers and cows http://purl.org/coar/resource_type/c_6501
